Hi all, is it possible to override an arbitrary property using an environment variable? For example in yaml I have postgres.database: my-db that I'd want to override with an env var POSTGRES_DATABASE: my-real-db. I know I can do postgres.database: "$POSTGRES_DATABASE:my-db" but that seems like a lot of noise for every possible property.

How would you like to solve it?

Similarly to what Spring does: https://docs.spring.io/spring-boot/reference/features/external-config.html#features.external-config.typesafe-c[…]laxed-binding.environment-variables

Unfortunately, Ktor does not have such functionality (using environment variables based on the properties' names). You can file a feature request.
